Product Overview

Alli is a product that has hit the diet pill market with quite a splash in recent years. Alli is the reduced-strength version (60 milligrams vs. 120 milligrams) of orlistat (Xenical), a prescription drug to treat obesity. It’s approved for over-the-counter sale to overweight adults 18 years and older. Alli can help you lose weight when used in conjunction with a low-fat diet and exercise.

The average weight loss for prescription-strength Xenical is about 5 to 7 pounds (about 2 to 3 kilograms) greater than diet and exercise alone after one year. (2, 4)

Alli promotes weight loss by decreasing absorption of fat by the intestines, which reduces the number of calories you absorb.

Lipase, an enzyme found in the digestive tract, helps break down dietary fat into smaller components, so it can be used or stored for energy. Alli works by disabling lipase, which prevents the enzyme from breaking down the fat while it’s in your digestive tract. The undigested fat continues through the intestines and is eliminated through bowel movements.

The user reports do show a significant amount of weight loss in subjects who used Alli for more than 3 weeks. Because of how Alli works, the directions recommend that you eat no more than 15 grams of fat with each meal. Eating greater amounts of fat can cause unwanted effects, such as urgent bowel movements, diarrhea and gas with oily spotting.

In 2009, the Food and Drug Administration (FDA) began a safety review of orlistat because of rare reports of serious liver injury in people using it. The FDA found no cause-and-effect relationship between orlistat and the risk of liver injury. However, Alli and Xenical labels now advise people to be alert to signs and symptoms that could indicate liver injury, such as itching, loss of appetite, yellow eyes or skin, light-colored stool, or brown urine.

Beware of Alli and it’s interactions with other prescription medications you might already be taking. The most common reported side-effects with Alli are gas, loose stool and frequent bowl movements.

Alli could definitively support your weight loss goals but by attention to side-effects.

    It’s true…Alli does curb the appetite. At least it works for me.
    As other have said, it’s not the end all diet weight loss magic pill. If you cut your calorie intake and up your cardio activity you should see weight loss results.

    Alli is awesome! Used with raspberry cleanse it’s even better! I noticed results after week # 2… Follow the instructions and drink plenty of water.

    I really don’t understand the reviews on other sites on Alli. No way it worked that great for so many people and did NOTHING for me.

    I really don’t see a difference in taking Alli. i work out on a regular basis and thought that these would give me that extra push to lose those last 10 lbs but not the case so far.
